ILLIA E. PACK, or OAKLAND, CALIFORNIA noonnns GAUGE Application filed. July 2e,

I This invention is for a roofers gauge and has for its main object theprovision of a gauge for the use of carpenters and roofers whereby a set of rafters maybe scribed or marked for cutting the various bevels at a single setting of the gauges:

Another object of the invention is to provide a device of the class described which may be folded into a flat packagewhichmay conveniently be carried in the pocket or tool bag, which is economically constructed, easi-' ly operated and accurate for'its purpose.

Other objects of the invention will become apparent as the following description is read on the drawing forming a part of this specification.

The invention is adequately illustrated in the accompanying drawing, in which;

Fig. 1 is a longitudinal elevation of the gauge as set for thehip-end of a rafter.

Fig. 2 is a bottom plan view of the inventionshowing the cap mortise gauges.

Fig. 3 indicates the gauge infolded position, and,

n Fig. 4 is a transverse sectiontaken on line 4-4 of Fig. 1.

Similar reference characters are used to designate similar parts throughout the several views. I r

The invention consists of a rectangular main straight-edge me'mber 6-to which is affixed. on the bottom thereof, a pair of, fillers i, in which are fixed the screws 8 provided with wing nuts 9/ One end of the 7 main straight edge member is slotted as at 10, and a hinge 11 is attached to the bottom thereof and extends over the inner edge of the slot. A pair of straight-edges 12 are pivotally attached to the bottom of the main straight-edge 6 as at 13, the straight-edges 12 having the struts 1e pivotally attached at 15. The struts 14 are slotted as at 16 to slidably receive the screws 8 and be clamped by the wing nuts 9, the fillers 7 being of substantially equal thickness to the straightedges 12. Aflixed to the upper surface of the main straight-edge 6 is a rail 18 which is adapted to slidably receive a shoe 19 which is provided with a wing screw 20 whereby the shoe may be clamped in any adjusted 1930.

position. Pivotally attached to the shoe 19 at 21 is a strut22, the opposite end of which is hinged to a straight-edge 23 as at 24, the opposite end being pivoted by means of the hinge 11. l

' The device is shownfoldedin Fig. 3, and is adjusted for use by swinging the straightedge 23 about the pivot of the hinge 11 through slot 10. and over the track 18, to the position shown in Fig. 1', the shoe 19 being 9 slid backward over the forward edge of track 18 to a point at which the proper pitch is obtained with straight-edge 28 relativeto the. upper surface of straight-edge 6. Straight-edges 12 are adjusted relative to 5 the sides of straight-edge 6 and the wing nuts 9 tightened. v

' The opposite surfaces 26 of straight-edge 6 are placed against the edge of the timber to be beveled and the bevel obtained by means 9 of straight-edge 23. In using the straight edges 12 either of the sides 26 is placed against the timber according to whether a right or left slope is required, and the slope obtained by the straight edges 12, by adjusting the members 12 to the desired slope and securing by means of nuts 9.

This device is particularly adapted for laying out the cheek cuts on jack rafters,

which obviously require a diagonal cut as related to one corner of the rafter. In the cutting of the common rafters, it is only necessary to obtain the. diagonal cut as related to one edge, this diagonalcut being complementary to the slope angle. v This same cut is provided in a jack rafter, except that the diagonal cut on one side of the rafter is not me plane at right angles to the side, and must be cut from one side to the other at an angle conforming to the angleof the hip rafter. v

It is for this purpose that the members 12 are provided, one of the members being used for the ack rafters on one side of the hip rafter, and theother member being used for the scribing of the jack rafters to be in stalled on the other side of the hip rafter, in other words, it is made to take care of right hand and left hand ack rafters. I The members 23 or 22 are used in relation to th e we straight edge 26, being set to the complementary angle related to the slope angle of the roof for marking the end cuts on the common rafters, as also for the ack rafters, and the members 12 are adjusted to the angle of the hip rafter as related to the jack rafter, and after these adjustments are made, the device is ready for marking the end cuts of all the jack rafters, the straight-edge 26 being laid fiat on the top edge of the rafter and a line scribed along the member 23.

At the coincidence of the scribe line with the top edge of the rafter, the side of the straight-edge 26 is placed against the side of the ack rafter with the straight-edge 12 in registry with the previously referred coincidence and the diagonal cut scribed, followed by placing the straight-edge 26 on the other side of the rafter inscribing the complementary cut andfinishing with the bottom of the rafter, whereby the exact cut is provided to cause the jack rafter to match perfectly and coincidently with the slope of i the roof and the angularity 0f the hip rafter.

Although this device in similar combination may be used for many purposes, itvwill be seen that it is especially desirable for use in scribing the end cuts of the ack rafters,

. being especially convenient, inasmuch as will be understood that variations in construction and arrangement of parts which are consistent with the appended claims, may be resorted to without detracting from the spirit or scope of the invention, or sacrificing any of the advantages thereof.

I claim 1. A gauge comprising a main straightedge, a track fixed to the upper surface thereof, a shoe slidable on said track, means for retaining said shoe in adjusted position on said track, a second straight edge, a strut pivotally connected at one end to said shoe, the other end being pivotally connected to said second straight-edge, said second straight-edge being hinged to said main straight-edge adjacent one end, oppositely disposed straight-edges pivotally attached to the undersurface of said main straight-edge adjacent said one end, struts pivotally connected at one end to said oppositely disposed straight edges, the other end of each of said struts having a longitudinal slot formed therein, a screw in said main straight edge and engaging through each slot and a wing nut for securing each of said oppositely disposed straight-edges in adjusted position.

2. A gauge comprising a main straightedge provided with parallel edges, a track fined to the upper surface thereof and centrally disposed thereon, a shoe slidable on said track, a clamp screw in said shoe, a

second straight-edge, a strut having one end pivotally mounted in said shoe, the other end of said strut being hingedly connected to one end of said second straight-edge which has its other end hingedly connected to one end of said main straight-edge, a pair of oppositely disposed arms pivoted to the undersurface of said main straight-edge, struts pivoted to said arms, retaining members for said struts, the end of each of said struts having a longitudinal slot for cooperation with said retaining members, said arms operating in a plane at right angles to said second straight-edge.

3. A gauge comprising a main straightedge, a track extending longitudinally of and secured to the top surface thereof, a shoe slidable on said track, securing means for said shoe, a strut having one end pivoted to said shoe, asecond straight-edge having one end pivoted to the other end of said strut, the other end of said second straight-edge being pivotally connected to one end of saidmain straight-edge and adapted to fold against the undersurface thereof, a pair of oppositely disposed arms each having one end pivotally secured to the undersurface of said main straight-edge adjacent one end and operating in a plane at right angles to said second straight-edge, and an adjustable strut for each of said arms.

4. A roofers gauge adapted for folding into a compact package comprising a main straight edge, a folding straight edge intermediately hinged and hinged at one end to one end of said main straight edge and havthe other end adjustahly and remo-vably secured to the top of the main straight edge, permitting said folding straight edge to be folded against the bottom of said main straight edge, a pair of obliquely adjustable straight edges pivotally secured adjacent each side of said one end of said main straight edge and adapted to fold against said folding straight edge when folded against the bottom of said main straight edge. i p

In testimony whereof I affix my signature.
